  • Patent number: 11694911
    Abstract: A substrate processing system for selectively etching a substrate includes a first chamber and a second chamber. A first gas delivery system supplies an inert gas species to the first chamber. A plasma generating system generates plasma including ions and metastable species in the first chamber. A gas distribution device removes the ions from the plasma, blocks ultraviolet (UV) light generated by the plasma and delivers the metastable species to the second chamber. A substrate support is arranged below the gas distribution device to support the substrate. A second gas delivery system delivers a reactive gas species to one of the gas distribution device or a volume located below the gas distribution device. The metastable species transfer energy to the reactive gas species to selectively etch one exposed material of the substrate more than at least one other exposed material of the substrate.

  • Publication number: 20220229399
    Abstract: A watch bezel provides a GMT function and a count-up time-tracking function. The watch bezel includes a first set of indicia to indicate 24 hours associated with the GMT function of the watch and a second set of indicia to indicate 60 minutes in an hour. When mounted or attached to the watch casing or body, the bezel is rotatable in the clockwise direction and in the counter-clockwise direction. The watch bezel enables a user to read or set the time associated with a secondary time zone without adjusting any hands on the watch. The second set of indicia comprises a plurality of incremental minute markers and allows a user to track elapsed time. The capability of tracking elapsed time allows the watch to be used in activities that require tracking of elapsed time such as diving or other sporting events.

  • Patent number: 11165682
    Abstract: A method performed by a network device includes: receiving a first packet by the network device, wherein the first packet is tapped from a network; identifying a session to which the first packet belongs when the first packet has one or more values that at least partially match one or more terms, wherein the act of identifying the session is performed by the network device; receiving a second packet by the network device; determining whether the second packet belongs to the session; and performing a packet processing action by the network device based on the identified session; wherein the session is identified based on a first criterion, and the act of determining whether the second packet belongs to the session is performed based on a second criterion that is different from the first criterion.

  • Patent number: 10813089
    Abstract: Embodiments include a method, computer program product, and system for grouping electronic devices into roll-call channel access (RCCA) groups to reduce the number of devices contending for a wireless channel. Devices within RCCA groups are represented a host device during a channel contention process. Once a channel is granted access to a host device, its respective RCCA group has control of the channel for a predetermined period of time during which devices of the RCCA group take turns transmitting data on the channel.
